Online dew point meter
This polymer dew point capacitor is the result of more than twenty years of arduous research. Usually, polymer capacitors find it difficult to measure dew points below -40°C Td. Because the rate of change is too low, the signal is hard to distinguish in the circuit. We conducted extensive fundamental research and finally mastered the technology to improve low-humidity sensitivity. Currently, when changing from -70°C Td to -50°C Td, the base capacitance changes from 300 pF to 305 pF, surpassing all polymer dew point capacitors on the market.
